Leather collar
For many participants in sexual activity, costuming is very important, and leather often is part of that costuming. It generally implies a male-oriented, usually gay scene among males, but can also be worn by women, especially if they are playing a dominant role. Leather accessories include jackets, pants, collars, hats and sometimes implements such as whips. ‘Leather’ has taken on a meaning beyond the material. It can also refer to the gay BDSM scene in general.
